What Are Garage Flood Vents?
Garage flood vents are specially designed openings in garage walls or doors that allow floodwaters to enter and exit freely. Their goal is to balance water pressure within and outside a structure during a flood to prevent substantial structural damage.
How Do Garage Flood Vents Work?
When floodwaters rise outside a garage, pressure develops against its walls. If water cannot enter to equalize the pressure, the walls or foundation may crack or collapse. Flood vents allow water to pass safely, lowering the danger of damage. This is especially important for garages attached to homes.
Are There Different Types of Garage Flood Vents?
There are two main types of garage flood vents: engineered and non-engineered. Engineered vents have undergone testing and certification to fulfill FEMA and NFIP (National Flood Insurance Program) criteria. They normally open automatically whenever floodwaters reach a certain level. Non-engineered vents might not offer the same level of protection or insurance compliance.
What Other Benefits Do Garage Flood Vents Offer?
In addition to structural protection, flood vents speed up the drying process in garages after a flood, lowering the risk of mold and long-term water damage. Additionally, they come in a range of materials and finishes, allowing them to be practical while maintaining the beauty of a home.
